I found this while googling. http://lists.trolltech.com/pipermail/qt-jambi-interest/2008-June/000395.html
It looks a lot like my bug and it seems it has been known for a while !! (June 2008) Do you know if there was a fix for this. Maybe I can fill a bug report. Is there a place where I could do this ?
